Leveling machine

High - precision leveling: By adopting advanced leveling technologies such as multi - roll leveling, hydraulic leveling or CNC (Computer Numerical Control) leveling, the flatness of the plates can be precisely controlled, with an accuracy of up to 0.05mm or even higher. Through an accurate control system and high - quality components, the flatness of each plate is ensured to be consistent, reducing the rejection rate.

No damage to the plate appearance: A large number of stagger - arranged leveling rolls are used to achieve repeated bending. The amount of bending can be adjusted to realize the bending scheme required for leveling, thus avoiding damage to the appearance of the plates.

Stress elimination: After the metal plates are repeatedly bent, the lengths of the metal fibers gradually become consistent, and the internal stress of the material is eliminated simultaneously, improving the quality and stability of the steel.

Improved production efficiency: With a high degree of automation and equipped with an advanced automatic control system (such as a PLC control unit), one - key operation, automatic feeding and discharging can be realized, reducing manual intervention. Through the CNC system, operators can quickly adjust leveling parameters (such as pressure, roll spacing, etc.) to adapt to plates of different thicknesses and materials. In addition, high - quality components and a stable structural design ensure that the equipment can operate continuously for a long time, reducing downtime.

Labor cost savings: It can be integrated into the continuous production line, saving a large amount of labor costs and getting rid of the technical dependence on traditional leveling experience.

Simple and convenient operation: All actions are centrally controlled by the operation console. The operation is simple and convenient, and the displacement is displayed digitally, reducing the labor intensity and operation difficulty of the operators.

Strong material adaptability: It can adapt to a variety of materials, including stainless steel, non - ferrous metals, carbon steel, etc., meeting different production requirements.

Energy - saving and environmental - friendly: It adopts high - efficiency motors and drive systems, with low energy consumption. Long - term use can save a large amount of electricity costs. Through optimized design, the operating noise of the equipment is reduced, improving the working environment.

Working Principle

Multiple - roll Repeated Bending: Through multiple sets of leveling rolls arranged in an up - down staggered manner, the steel undergoes continuous bending in positive and negative directions as it passes through. During this repeated bending process, the internal stress of the metal sheet is eliminated, and the lengths of the metal fibers tend to become consistent, thus achieving the flattening of the steel.
Roll Pressure Adjustment: The amount of roll pressure can be adjusted according to the thickness and material of the steel. Thicker materials require a larger amount of roll pressure, while thinner materials need more precise adjustment, so that the steel gradually approaches the ideal flat state each time it passes through the leveling rolls.

Structural Composition

Leveling Roll System: It is the core component, usually composed of multiple upper rolls and lower rolls. The surface of the rolls has undergone special treatment, featuring high hardness and wear resistance to avoid damaging the surface of the steel during the leveling process.
Drive System: It is used to drive the rotation of the leveling roll system, enabling the steel to pass smoothly between the rolls. Generally, equipment such as motors and reducers is used, and power is transmitted to the leveling rolls through couplings or gear transmissions.
Lifting System: It can adjust the gap between the upper and lower leveling rolls to meet the leveling requirements of steels with different thicknesses. It is usually composed of components such as hydraulic cylinders and screw - nut pairs, and the lifting movement of the upper roll is achieved through hydraulic or electric means.
Feeding and Discharging Devices: They are responsible for conveying the steel to be leveled into the leveling machine and sending out the leveled steel. These devices include conveyor roller tables, guiding devices, etc., ensuring that the steel accurately enters and exits the leveling machine.
Control System: It is used to control the overall operation of the steel leveling machine, including the rotation speed of the leveling rolls, the actions of the lifting system, and the feeding and discharging speeds. Usually, equipment such as PLC (Programmable Logic Controller) and touchscreens is adopted. Operators can input parameters and commands through the touchscreen to achieve automated control.

Types

Classification by Structural Form: There are two - roll type, three - roll type, four - roll type, multi - roll type, etc. The multi - roll type has a good leveling effect and is suitable for steels of various thicknesses and widths. The two - roll type and three - roll type have a simple structure and are used in occasions where the requirements for leveling accuracy are not high.
Classification by Drive Mode: It can be divided into mechanical drive type, hydraulic drive type, and electric drive type. The mechanical drive type has a simple structure and low cost, but the leveling force is relatively small. The hydraulic drive type has a large leveling force and can adapt to the leveling of high - strength steels, but the maintenance cost of the hydraulic system is high. The electric drive type has high precision and fast response, and it is a more advanced drive mode.
